ADJUSTABLE CHAIR.

SPECIFICATION forming part of Letters Patent N o. '71 1,412, datedOctober 14, 1902.

Application filed January 13,1902. Serial 110.89.545. (No model.) 7

To all whont it may concern:

Be it known that I, JOSEPH EDWARD ARCH- AMBEAULT, a citizen of theUnited States, residing at South Bend, in the county of St. Joseph andState of Indiana, have invented a new and useful Adjustable Chair, ofwhich the following is a specification.

My invention is an improved adjustable chair having an adjustable seat,back, and foot-rest which may be adjusted to either a sitting orreclining position, according to the desire of the occupant; and itconsists in the peculiar construction and combination of deviceshereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of anadjustable chair embodying my improvements, parts of the frame beingbroken away and shown in section. Fig. 2 is aside elevation, partlyinsection, of the same, showing the seat, foot-rest, and back disposed inreclining position and in dotted lines showing the same disposed inseating position. Fig. 3 is a transverse sectional view of the same.

In the embodiment of my invention I provide a suitable supporting-frame,which is here shown as comprising the legs I, the bars 2, which connectthe legs together, and the arms 3, which are disposed at the upperendsof the legs on opposite sides of the frame. A foot-rest 4 is carried bya pair of, arms 5, which constitute the frame of the foot-rest, and theupper ends of the said arms are provided with pivots (l, which operatein bearings 7 in the legs at the front corners of the frame. Thereby thefoot-rest is pivotally connected to and suspended from the frame and isadapted to be swung forwardly therefrom.

The backS of the chairin the embodiment of my invention here shown isprovided on its sides at its lower corners with links 9, which aresecured thereto and which at their upper ends are provided with pivots10, which have their bearings in the legs at the rear corners of theframe. The said links are provided with extended arms 11, which aredisposed parallel with the axis of the back, or substantially so, andthe lower ends of the link-arms are pivoted, as at 12, to the sides ofthe seat 13, near the rear corners thereof.

It will be understood that the back is by the links 9 pivoted at itslower corners between the sides of the frame at'the rear corners thereofand that the rear portion of the seat is supported by the said links.The arms 5 of the foot-rest are pivotally connected ata suitabledistance from their upperends to the sides of the chair-seat,near thefront corners thereof, as at 14, and thereby the front portion of theseat is supported by the said arms of the footrest. Hence the chair-seatis adapted to be swung forwardly and rearwardly between the sides of theframe, and being connected by the links 9, which suspend and support itsrear portion, to the back the latter swings simultaneously with theseat. It will be understood that the foot-rest swings simultaneouslywith the seat and back and that the latter forms a lever by means ofwhich the occupant of the chair by leaning rearwardly may move thesuspended chair-seat and the foot-rest forwardly and upwardly to disposethe back, seat, and foot-rest in reclining position, as shown in fulllines in Fig. 2. The back is provided with a head-rest 15, which ishinged.

or otherwise flexibly connected thereto, as at 16. A rod 17 has itslower end pivotally connected to the rear side of the seat, as at 18,and its upper end bifurcated to form arms 19,

each of which is provided with a slot 20. The

said slots are engaged by keepers 21 on the rear side of the head-rest,so that lost motion is provided between the operating-rod 17 and thehead'rest, and it will be understood that as the back and seat of thechair are adjusted to a reclining position the rod 17 will turn thehead-rest upwardly at the upper end of the back, so as to raise somewhatand support the head of the occupant.

A pair of racks 22 are provided at their front and rear ends with arms23, which are attached to the bottom of the seat and support the racksin an inclined position under the seat. A pair of yokes 24 arefulcrumed,

as at 25, on the inner sides of the side bars of the chair-frame andhave their front ends connected together by a transversely-disposedlock-bar 26, which isadapted to engage the teeth on the upper sides ofthe racks 22 to se cure the seat, and hence also the back andTripfoot-rest, at any desired adjustment.

rods 27 have their lower ends pivotally connected to'therearwardly-extending arms of the yokes 24:, as at 28. The upper portionsof the said trip-rod extend through and are guided in vertical openingsin the chair-arms 3, the upper ends of said trip-rods projecting abovethe chair-arms a slight distance and being thereby adapted to bedepressed to cause the lock-bar 26 to be raised by the yokes 24 out ofengagement with the racks 22, and thereby enable the chair to beadjusted to another position. Spring-arms 29 are here shown as havingtheir outer ends secured to the inner sides of the rear chair-legs andtheir front ends connected to the lockingbar 26. The function of thesaid springarms is to keep the locking-bar normally in engagement withthe locking-racks 22.

I do not desire to limit myself to the precise construction andcombination of devices herein shown and described, as it is evident thatmodifications may be made therein without departing from the spirit ofmy invention.

Having thus described my invention, I claim 1. In an adjustable chair,the combination of a frame, a foot-rest and back each pivotallyconnected thereto, a seat pivotally connected to and suspended andsupported by the foot-rest and back, whereby the seat, back andfoot-rest may be simultaneously adjusted, a head-rest flexibly connecteddirectly to the back, and an operating-rod connecting the head-rest andseat, whereby the head-rest is automatically adjusted simultaneouslywith the back, seat and foot-rest, is extended from the back in linetherewith when the back is raised and is turned upwardly at an angle tothe back when the latter is lowered, substantially as described.

2. In an adjustable chair, the combination of a frame, a foot-rest andback, each directly pivoted thereto, a longitudinally movable seatpivotally connected to and suspended and supported by the foot-rest andback, whereby the seat, back and foot-rest may be simultaneouslyadjusted, a downwardly and rearwardly inclined rack carried by the seatand a detent pivoted to the frame and adapted to engage the rack andthereby lock the seat,

back and foot-rest at any desired adjustment, substantially asdescribed.

3. In an adjustable chair, the combination of a frame, having side arms,a foot-rest and back, each directly pivoted to said frame, alongitudinally-movable seat pivotally connected to and suspended andsupported by the foot-rest and back, whereby the seat, back andfoot-rest may be simultaneously adjusted, a downwardly and rearwardlyinclined rack carried by the seat and having forwardlyextending teeth, adetent to engage the rackteeth and pivoted to the frame, and a triprodconnected to the detent and one of the arms of the frame, substantiallyas described.

4. In an adjustable chair, the combination of a frame, alongitudinally-movable seat, a back pivotally connected to the frame andto the seat whereby the seat and back are adj ustable simultaneously, anadjustable headrest'carried by and flexibly connected directly to theback, and connections between the head-rest and the seat whereby thehead-rest is automatically adjusted simultaneously with the seat andback, is extended from the back in line therewith when the back israised and is turned upwardlyat an angle to the back when the latter islowered, substantially as described.

5. In an adjustable chair, the combination of a frame, alongitudinally-movable seat, a back pivotally connected to the frame andto the seat, whereby the latter and back are adjustable simultaneously,an adjustable headrest carried byand flexibly connected directly to theback, and a yieldable connection between the head-rest and the seat,whereby the head-rest is automatically adjusted simultaneously with theseat and back, is extended from the back in line therewith when the backis raised and is turned upwardly at an angle to the back when the latteris lowered, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

JOSEPH EDWARD ARCHAMBEAULT.
